Trial Outcomes & Findings for Social Media Based Peer-Led Intervention for HIV Prevention (NCT NCT03213366)

NCT ID: NCT03213366

Last Updated: 2019-11-06

Results Overview

This primary outcome is intention to use PrEP in the next month measured at baseline, 6 weeks, and 12 weeks. This was assessed with a yes/no question (dichotomous variable). However, this variable does not include anyone who reported PrEP use at either 6 or 12 weeks. This outcome will inform sample size calculations for a subsequent fully powered trial.

E-PrEP- Peer-Led Intervention About PrEP
We recruited Peer Leaders over a 5-week period and then randomly assigned them to the 2 arms. Peer Leaders were blinded to their study condition. Peer leaders recruited study participants via their existing online social networks to complete an online eligibility screener and baseline survey. Study participants were then directed to join a private online group, facilitated and moderated by the peer leader who had recruited them. Content: The E-PrEP campaign focused on delivering information about PrEP. The materials were composed of 6 weeks of publicly available PrEP educations materials selected by peer advisors prior to the intervention (i.e. information on how to talk to your doctor about PrEP, where to get PrEP, side effects, etc.). The materials mapped out onto Diffusion of Innovation (DOI) and Information, Motivation, Behavior (IMB) domains. Peer leaders framed the E-PrEP materials in their own words when posting the materials to their online private group.
BxNow-General Health Control Arm:
We recruited Peer Leaders over a 5-week period and then randomly assigned them to the 2 arms. Peer Leaders were blinded to their study condition. Peer leaders recruited study participants via their existing online social networks to complete an online eligibility screener and baseline survey. Study participants were then directed to join a private online group, facilitated and moderated by the peer leader who had recruited them. Content: BxNow focused on a broad range of health topics prioritized by the peer leaders assigned to this arm, but did not include any contents about HIV or PrEP (i.e. depression, anxiety, suicide, intimate partner violence, drug use, awareness of sexually transmitted infections). BxNow was attention matched to the E-PrEP intervention timeline (6 weeks of materials) for both time and day of posts and frequency of posts. As with E-PrEP, standardized BxNow contents were delivered by peer leaders, framed using their own words.

Self-reported PrEP related knowledge. Participants were asked two questions about PrEP knowledge. For each question, they got one point if the answer was correct. Scale range from 0-2. The score were added and the average of the sum was reported. The higher the score, the higher the knowledge of PrEP.

Any stigma the participant might have about PrEP or those who use PrEP To measure PrEP Stigma we asked 3 questions, using a Likert scale (from 1-4; 1= Strongly Disagree, 4=Strongly Agree). The scores were summed for each participant. The scores range from 1-12, with higher scores indicating higher levels of PrEP Stigma. The higher the score, the higher the level of PrEP stigma.

Discussion of PrEP with friends, partners, or family. Communication about PrEP was measured with 2 questions, using a Likert scale ( from 1-5;1=Not at all, 5= Extremely). The scores of the 2 questions were summed for each participant. The scores range from 1-10, with higher the score indicating higher the level of communication about PrEP (i.e. higher scores indicates participants communicating more about PrEP).

SECONDARY outcome

Timeframe: baseline, 6 weeks, 12 weeks

Any Barriers to PrEP uptake. To measure barriers to PrEP uptake, 7 items were used. Each item was measured using a likert scale ( from 1-4; 1=Strongly Disagree, 4= Strongly Agree). The scores of each question were summed for each participant (scale scores ranged 1-28, with higher scores indicating higher levels of PrEP Barriers). The higher the score, the higher the number of PrEP Barriers.

E-PrEP- Peer-Led Intervention About PrEP
n=65 Participants
We recruited Peer Leaders over a 5-week period and then randomly assigned them to the 2 arms. Peer Leaders were blinded to their study condition. Peer leaders recruited study participants via their existing online social networks to complete an online eligibility screener and baseline survey. Study participants were then directed to join a private online group, facilitated and moderated by the peer leader who had recruited them. Content: The E-PrEP campaign focused on delivering information about PrEP. The materials were composed of 6 weeks of publicly available PrEP educations materials selected by peer advisors prior to the intervention (i.e. information on how to talk to your doctor about PrEP, where to get PrEP, side effects, etc.). The materials mapped out onto Diffusion of Innovation (DOI) and Information, Motivation, Behavior (IMB) domains. Peer leaders framed the E-PrEP materials in their own words when posting the materials to their online private group.

n=63 Participants
We recruited Peer Leaders over a 5-week period and then randomly assigned them to the 2 arms. Peer Leaders were blinded to their study condition. Peer leaders recruited study participants via their existing online social networks to complete an online eligibility screener and baseline survey. Study participants were then directed to join a private online group, facilitated and moderated by the peer leader who had recruited them. Content: BxNow focused on a broad range of health topics prioritized by the peer leaders assigned to this arm, but did not include any contents about HIV or PrEP (i.e. depression, anxiety, suicide, intimate partner violence, drug use, awareness of sexually transmitted infections). BxNow was attention matched to the E-PrEP intervention timeline (6 weeks of materials) for both time and day of posts and frequency of posts. As with E-PrEP, standardized BxNow contents were delivered by peer leaders, framed using their own words.

SECONDARY outcome

Timeframe: at baseline, 6 weeks, and 12 weeks

Self-reported answer to questions about self-efficacy of using PrEP. There were two questions to measure self-efficacy of PrEP using a Likert scale (ranging from 1-5; 1=Not at all, 5=Extremely). The scores from both questions were summed for each participant. The scale range from 1-10 with higher scores indicating higher the levels of PrEP self-efficacy.

OTHER_PRE_SPECIFIED outcome

Timeframe: at baseline and 6 weeks

Population: The total number of participants who completed baseline study was 81 for e-prep and 71 for control. The analysis for 6 weeks included only the people who completed the survey at each that time period.

The scale measure the level of trust the Participant had on the Peer's online post. Trust in the Peer Leader was measured using 4 questions, each scored from 1-7 (1=Strongly Disagree, 7=Strongly Agree). The score for the 4 questions was summed for each participant. The score ranged from 1-28 with higher scores indicating a higher level of trust the participant had in their Peer Leader.
